• Outperforms fibreglass, washable and non-electrostatic 3 month pleated 1 in home air filters for your furnace, air conditioner, or HVAC system
• Designed with exclusive Filtrete™ brand three-in-one technology to trap unwanted air particles while letting cleaner air flow through
• Attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog
• The higher the MPR, the more microparticles such as pollen, pet dander, smoke, bacteria and viruses, your filter will capture from the air passing through it
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool, wasting energy, sign-up for a filter change reminder program that works for you
